The Sun Concept CAT 12.0 Lounge is a 12-meter solar-electric catamaran built for commercial passenger operations. With a capacity to transport up to 40 people, it combines an open, spacious interior layout with eco-friendly propulsion, offering comfort, utility, and zero emissions. 

With a length of 11.90 m, beam of 5.95 m, and draft of 1.10 m, the CAT 12.0 Lounge supports stable performance while offering generous deck volumes. Its 6 kW solar roof supplements the propulsion system to extend endurance and reduce reliance on external charging. 

Designed with modular layouts in mind, the vessel delivers flexibility making it ideal for tours, excursions, or event charters. Its open lounge design maximizes passenger space and flow, while maintaining the structural efficiency of a catamaran hull. 

Performance is smooth and accessible. The CAT 12.0 Lounge achieves a max speed of 14.5 knots, and at lower speeds, its solar and battery system can deliver virtually unlimited navigation. 

Equipped with base amenities like 2 cabins, WC & shower, refrigerator, freezer, and a large solar panel array (40 × 150 W), the Lounge model offers both utility and comfort in an eco-conscious footprint.
